Hi GUYS,
I have a Galaxy S4 GT-I9500 with android 5 official and TWRP Recovery installed. I just want if there are any settings in Synapse App for better performance and long battery life.
I have NevermoreX TW kernel installed.
I just want a good standby time with good SOT.

Hi @AgentDivanshu ,
For battery life you can underclock to 1200 MHz and then undervolt the cpu, it makes huge difference, just make sure you dont set it on boot before trying.
Keeping these settings, use ondemand with row, which will not affect the performance while saving battery for you.
Try it for sometime, see if it lags or something, if everything is fine then you can set it on boot.
Hit thanks if it helped.

Battery life on this phone is abysmal - on a fresh phone. Didn't restore much from titanium backup.
Would like to drop the CPU down a good 25% or so, can this be done without too much stress? It's an unbranded, rooted i9505 in Australia.
I suspect I'll need to flash something to do so, is that right?

Define "superb" for me.
Apologies for jumping in here. Can you define abysmal too? I would say my battery life is more than double my S2 (that was Cyanogen niggtlies but this is currently djembey's slim). Biggest drain is usually the 3G but I have that off most of the time. It is hard to compare to be fair as we will all use different settings but I have a lot of the bloat removed or disabled, power save on and screen at half brightness. How is yours setup as maybe we can shyc settings a little to compare more closely.

If the reason to underclock is to save more juice, you should understand that the phone doesn't work on 1,9ghz most of the time, on average it's 200-800mhz depending on task, so you would not probably win a lot battery if you underclock let's say to 1.7 unless you're a heavy gamer.

I know this tread is already pretty old, but that answer is only partially true.
On stock configuration the GS4 uses the 'ondemand' cpu gouvernor. That gouvernor ramps up the cpu speed to the max when cpu activity is detected and will then slow down the cpu depending on the task. So everytime you open/close an app the cpu is running at 1.9ghz. (At least that I heard/experienced) using a custom kernel you can choose a different gouvernor which is more battery friendly, or lower the max cpu speed(from 1.9 To for example 1.7ghz). You can also lower the min cpu speed so that when the device is idle, it will consume less power (I think standard is around 350mhz and I put mine on 189). Some kernels even allow to underclock the GPU. Undervolting will also save battery.
In short: using a custom kernel you can really save some battery, increase performance, or get a better balance between the two, but you will have to take the time to find the settings that work best for you. I personally use KT kernel, with an overclocked CPU and GPU, but I also undervolted them both by 75mV, and with some tweaking with settings for when the screen is turned off, my battery lasts longer than stock configuration.
Correct me if I'm wrong on something, I'm not a Cpu expert
And sorry for bad english

Check this out, if you long press the power saving icon in the notification pull down, it will bring the settings for it, Uncheck all but the cpu. It will run no higher than about 1.3 ghz and is plenty fast for all tasks. I use that setting on the s4 and note 3. I never ran into any lag except TouchWhiz home launcher but I use Nova Launcher anyways.
You will see a better battery life as well.
Currently running 4.4.2. stock with ART enabled. This combo suits me well in terms of fluidity and everything works great. Now I would like to have an option on disabling 2 cores to extend battery life. is there an app to do so on stock kernel and is it even possible to do it on some custom kernel? If there's no option to do it on stock id like recommendation for custom kernel that works on stock rom and would enable me to do this via some app.
And id like that ART can stay enabled.

try a custom kernel like ak or hellscore
after that disable 2 cores using trickster mod/kernel specific app
Yes, Darkrai is right. Test a custom Kernel like AK, Matr1x, Hells core, Franco or Faux.
You can easily flash the zip via recovery. After that, you should download a Kernel App like Trickster Mod or Kernel Tweaker from the Play Store to customize the whole kernel, gpu, cpu, govenors, schedulers (2wake) etc. And also the cores of the cpu. But you need not to stop 2 cores, you only have to underclock the cpu, so you have all 4 cores but they, for example stop at 1ghz, which save battery at all
I don't really think it helps your battery life (a lot).
More cores at a lower frequency are more power efficient than less cores that have to work at a higher frequency to get the same job done.
And hotplug is there for a good reason, if cores can sleep they will.
Or does anyone have personal experience where it really helped a lot?
I don't understand why people complain about battery life. They say 1 day is not enough, well it is considering their usage.
You can easily pull of 2-3 days without playing games. The problem is that everyone spends like 2-5 hours looking at their phones every day!
On topic: If you want to have performance and fluidity with 2 cores, you will save 0% battery because cores will work on higher frequencies. Just try not to using your phone 24/7

Short answer: No.
Long answer: No. But you can undervolt them (All 4 of them at the same time).

Try Franco kernel ... it by default supports dual core mode ... moreover u can play with hotplug values according to need
You can using a custom kernel, lots include the ability to but the best implementation is faux's eco mode which is found in Faux's kernel and Ak kernel.

I have tried semaphore kernel with 2 cores only online.
No big difference with other custom kernels where I was using all 4 normally. And the worse about 2 cores is the lag at many applications.

Great, its the kind of discussion i hoped to start. My logic was that n4 might have enough cpu power for surfing and casual usage with 2 cores only. So if i disable another 2 i might extend battery life.
Its great some of you tried and show me that my logic was flawed
Now undervolting. I suppose that i cant fiddle with stock kernel and undervolt cpu? Any recomendations for custom kernel. id like it to be as similar as stock, with undervolting feature enabled.
And are there any real gains in undervolting?

Many custom kernels support uv like Franco, hell God etc.
Uving is offering a little cooler cpu, which means more time till thermal throttling to start.
Let's say it helps system in general, but not something to notice in big way.
Unleashed by my Nexus 4
Undervolting brings much more than turning off cores. As a side effect your phone won't heat as quickly under heavy load.
What will save you a lot of power while having the phone awake is screen brightness. So you should look for a clever auto brightness solution or, like me, use a mod that let's you adjust brightness by swiping the status bar. I keep my screen dimmed to the low at all times and only make it brighter temporarily if I am outside and the sunlight blinds.

On Williams using mpdecision, smartassv2 governor, 281mhz min frequency, 1,7 max frequency, sio governor, multi core power saving "on", GPU clock 400mhz and 25mV undervolting i done 6h 47m on screen on from 100% to 15%.
I am using exitenz rom and this updated app : http://forum.xda-developers.com/showthread.php?t=2401988

Awsome! I recommend this settings if you want great battery life with nice performance.
What's the ROM you use? Just stock or stock based custom?

I had similar experiences when my phone was new and on android 4.1. But now 4 hours screen of stock is max
. i think xperias sp from different production lines or times can be really different. For a lot of peoples 4.1 works better, 4.3 works far worst. For me 4.3 works better but battery life suck. :/
Maybe because my phone was swimming last time i have bad battery life x. X

Hi
Mate , first thing you have to do is find out who is running wild in your phone use BBS

Let it run for a few hours and read the log to find out what is keeping awake the phone
Also review your settings , wifi , mail , FB , location.....
Good morning Le Pro3 forum -
I've been switching between Paranoid Android and Lineage OS for the past few weeks. One thing I've noticed very specifically is that PA 7.3.0 (and 7.2.0...) does not seem to effectively go into 'doze' as well as Lineage OS. What I mean is that battery drain overnight is pretty high on PA (10-20%) while Lineage is very low (less than 5%) using the same applications.
So that I can better understand and troubleshoot, would anyone be willing to point me to other forum posts either here or on other forums that dive into troubleshooting this kind of thing? I'm not finding anything that useful that is *recent*.
Thanks in advance!

Slightly tangential, but how is the battery life overall compared to LineageOS? I've been running LineageOS and while it performs well, the battery life isn't nearly as good as stock EUI. As for over night battery drain, I get about 10% in 8-9 hours in stand by.
Hey. I tried every single rom out there from MoKee to Lineage and i can asure u one thing. Best for battery is Omni ROM (latest) + BlackScreen kernel version 3.6
Now i am a medium - heavy user. Lots of time on snapchat and playin games for about half an hour to a hour. I got 6 hours of screen on time wich is great really compared to other roms.
Now i also tried various combinations of using different governors and so on so i tested an option for about three days and then tried another one. I was seeking for the best possible battery life while don't have any stuttering or lags. Cuz if u put the cpu governor for example on impulse and then underclock it too... It lags like hell.
Soo what do u need to do to get also good standby performance?? I loose less than 3% over night.
Try following:
IN KERNEL AUDITOR
CPU: Both big and little cores governor set on alucard
Underclock the big cores to 1900 and little cores to 1440
GPU: governor set to msm-adreno-tz; underclock max frequency to 560 MHz; enable Adreno idler
I/O sheduler: set governor to noop; read-ahead 128 kB
Low Memory Killer: set profile to Agressive
Misc: Vibration strenght set on about 15%, disable Fsync, TCP must be westwood.

Developer options:
Set logger buffer size to off
Set all three animation scales on 0.5x

Hi mate, thank you for your detailed review. It helped me especially for kernel auditor settings. But i have an objection in my honest oppinion. I have tried both roms, AICP 12.1 and OmniROM and AICP is much better at battery department. But both rom is great in the rest.

Really, well u know it is mostly how u use it. Cuz for my type of usage Omni works perfect. I was using AICP for a month before i tried other roms as described and it was really good but idk... When i was using it i got 4h and 30min at best with my kind of usage but with omni i got easily 6h. It depends from user to user but well... I will give AICP another shot anyway. I am glad that my review helped u.

yes it helped a lot. especially kernel tweaking thing. both rom is great imho and 1-1.5 hr screen on time difference may marry -as you said- on which programs/apps we use. we must be glad that our le pro 3 has a great nougat support from these beautiful devs and i dont know how to thank to them. i just used 2-3 days this AICP rom and i will give also a shot to OmniROM to compare them again. I love both roms and i am sure i will keep switching between the two
